/**
 * Activity (#249 Activity-1): the concept's Activity page (app.js renderActivity 732–738), its top-bar button
 * (`button#activity-open` with `span.count#activity-count`, index.html 51–52) and its sidebar row (app.js ~341), fed
 * by the session job store (activity-store.mjs).
 *
 * - D52: both counts show the running jobs only and are hidden at 0; the heading has no "Unified activity · proposed"
 *   chip (prototype copy).
 * - D53: while a job runs, the progress pill (`a.activity-pill`, the approved mockup's) sits before the button on every
 *   page: "Scanning · 42% · 8,240 / 19,622" and a mini bar, linking `#/activity/<id>`.
 * - D56: each item's title links its job's own view (activity-job-view.mjs).
 * - D54: each `.activity-item` is a real job. Its chip names the state (green "Completed", or blue "Running",
 *   "Cancelled", "Failed", "Ended"), its line says when and what, and a running job shows its `<progress>` and
 *   "Cancel job" (no "Simulate completion").
 * - D89: an image tagging job's line names its images and, once ended, "N tagged · M errors".
